Detailed Description

The invention is further illustrated below with reference to examples.

As shown in fig. 1-5, a long banquet dining table system according to the present application is characterized in that the long banquet dining table system is formed by connecting a plurality of table bodies 1 with the same structure in parallel or at an angle end to end, each table body 1 comprises a hollow box-shaped table plate 2, an adsorption plate 3 is fixed on the lower surface of the table plate 2, and a plurality of pulleys 4 can be adsorbed and fixed;

the pulleys 4 are rotatably provided with chain wheels 6 through rotating shafts, the chain wheels are horizontally arranged, one chain 7 passes through all pulleys which are substantially adsorbed on the left side of the table plate and is meshed with the chain wheels in all pulleys which pass through, the other chain 7 passes through all pulleys which are substantially adsorbed on the right side of the table plate and is meshed with the chain wheels in all pulleys which pass through,

the bottom of each pulley is connected with the supporting leg 5 through a ball hinge 8, and the supporting leg connected on the pulley which is generally adsorbed on the left side of the table plate is fixed in a crossing way with the supporting leg connected on the pulley which is closest to the pulley and is generally adsorbed on the right side of the table plate, so as to support the height of the table plate;

when the trolley is used, the hinging shafts of the two chains 7 connected with different chain links are vertically upwards, so that the heights of the whole chains are unified, then all the table boards are sleeved on the chains through the trolley, namely, the height of the table boards is unified, then the adsorption positions of the trolley on the adsorption plates are changed aiming at uneven ground, the extending lengths and angles of the supporting legs are changed, and the solid ground is supported reliably.

Chains are commonly used mechanical transmission mechanisms consisting of links, connecting plates and articulated shafts. However, the scheme does not adopt the continuous transmission, but adopts the other characteristics of: all links of the chain can only swing in one plane, so that when the hinge axis is vertically upward, the entire chain is generally (the tail will hang down slightly) in the same elevation plane. This feature is used to keep the table in the same plane without the need for additional leveling instruments.

In order to reliably support the tabletop plate on the same plane, a supporting leg system with uncertain supporting leg supporting points is arranged, when the ground is flat, referring to fig. 2-6, the pulley is adsorbed under the tabletop plate in order, the device is completely corresponding, and the supporting legs are also completely symmetrical, so that reliable support is achieved;

when the ground is uneven, such as a protrusion, referring to fig. 7-9, the pulley on the supporting leg which is propped against the protrusion changes the adsorption position, and drives the supporting leg to adapt to the protrusion terrain, namely, simultaneously forms a reliable support. Since the prepared chains are considered to be long enough, the adsorption position is changed as in fig. 9, but the chains of a certain length are used at one side, and other tables are not affected. In order to ensure that the above-mentioned arrangement works smoothly,

further, the beam frame is 8-shaped, and the two supporting legs penetrate through the two holes and can be penetrated and adjusted in the hole space in depth, and the beam frame is fixed through the fastener 10 after the penetration and adjustment.

Further, the fastener is a set screw with a stem.

In this case, the adjustment of the legs is very convenient.

In this case, the table can be prevented from collapsing due to curious screw loosening by children or the like.

Above scheme has solved the requirement of arranging long table in the not good street of level and smooth condition, and the chain that uses can be enough long, needs long table of how long, only a table body penetrates can, reaches the height of predetermineeing after penetrating.

In order to facilitate the situation when the street is not straight,

further, fan-shaped rotating blocks 11 are arranged at the head end and the tail end of the table body 1 and can be received in the sleeve cavity of the table box, and adsorption points 12 are arranged on the outer end surfaces of the fan-shaped rotating blocks and can be connected with connecting points 12 on the other fan-shaped rotating blocks 11.

Further, the fan-shaped rotating block is rotationally connected with the table body.

Further, the connection point is a magnet.

Further, the connection point is a magic tape.

Further, the connecting point is a hook.

In the case of the above-described sector plates, the connected table bodies do not need to be parallel, but can always be connected at the desired angle, as in figure 10, and because they are connected with a sufficiently long chain, the variable angle S-shaped connection does not affect the reliable operation of the device.

The novel desk top height setting device mainly completes innovation in two aspects, firstly, the novel desk top height setting device is formed by the basically non-sagging characteristic of the chain, so that the desk top height is very easy to unify, secondly, the novel desk top height setting device is adsorbed by the supporting legs, and the novel desk top height setting device can be suitable for various uneven ground and is convenient to adjust.

The foregoing describes one embodiment of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
